Must keep the story straight.
g77 is a proper Fortran compiler that implements Fortran-4, Fortran-77, IBM and
VAX extension, etc.
After the g77 author and maintainer retired, g77 was eventually deleted from
gcc. (as if nobody uses it anymore, go gcc, go!).
Meanwhile some young yahoos who have only seen a VAX on wikipedia wrote a
completely new compiler to the Fortran-90 specifications, now included in gcc
as "gfortran".
As all of you surely know, Fortran-90 has nothing to do with traditional
Fortran and this gfortran newthing
cannot compile most of the fortran code we still use daily. (nor does it
compile the Fortran-90 code
we have in one of our defunct experiments - that code was written using Absoft
and Intel f90 - unlike
gfortran, Absoft and Intel got it right - by including compatibility modes for
traditional fortran).
This is a sorry mess, same as if they deleted the gcc "c" compiler and told
everybody to use "g++" as replacement,
except that Fortran-90 comes without the clause about "incompatibilities
between C and C++ should be reduced as much as possible" - quoting Bjarne
Stroustrup at https://en.wikipedia.org/wiki/Compatibility_of_C_and_C%2B%2B
(again, Bell Labs got it right, unnamed GCC yahoos got it wrong).
